MARKING momma.

Application and :une 26, 192s. sei-iai No. 118,665.

This invention relates to marking machines for making impressions upon leather and other materials to indicate the outlines for the guidance of subsequent operations.

An object of the invention is to provide a machine for the purpose stated comprising a support for the material or articles to be marked, and a manipulative die supporting device movable from a position to receive a marking substance, such as ink, to a position to press upon the material to be marked and make an impression thereon with the marking substance to indicate the outlines for subsequentoperations.

- Another object of the invention is to provide a marking machine equipped with mea-ns for properly locating and holding the materials to be marked, so that the die will make the proper impressions in proper locations without the requirement of any particular care or attention by the operator after the materials have been located.

Another object of the invention is to p rovide an improved marking machine having a movable support for the dies,and means for attaching the dies to such support and operating the support and thereby the dies to mark the outlines for subsequent operations upon the materials supported in proper position for that purpose.l

Another object of the invention is to provide an improved marking machine having die supporting mechanism, and means'facilitating the operation of said mechanism to apply tok the dies a proper marking substance and to operate the dies to apply the marking substances to the materials to be marked for subsequent operations.

Other objects will appear from the. following description, reference being made to the accompanying drawings, in which Fig. 1 is a frontelevation otmy improved markin machine.

Fig. 6 shows a specimen of die marker, although it will bev understood that various shapes, designs and forms of die markers may be used on this machine.

vmachine at the proper height for convenient operation.

The machine comprises a base which, in the form shown, includes a die Supporting portion '2 at the front and a' marking substance supporting portion 3 at the rear. As

shown the means for applying a marking substance to the dies comprises a pan or tray 4 designed and arranged to contain a quantity of ink and an ink pad 5. The pan 4 may besecured to the base by screws 4.

The work locating and supporting devices are interchangeable and removable from the machine, so that materials cut to dilierent shapes and dimensions may be properly located by the use of an appropriate specially designed locating device. Each of such locating devices, one of which is shown, comprises a gage plate 6 having on its upper side forms 7 to receive niarginal or projecting` portions of the materials to be marked and thus expedite and facilitate proper location of the materials for operation of the marking device. Each of said plates 6 is provided with a number of holes arranged to receive pins 8 extending from the frame supporting part 2 and thus hold the plates 6 immovable in proper location.

The die carrier comprises a frame 9 swingingly supported by a air of front arms 10, the upper ends of which are pivoted to the lateral ends of the die carrier and the lower ends of which are connected to the base by pivots 11, and a pair of rear arms 12 having their upper ends pivoted to the die carrier 9 and their lower ends attached to a rock shaft 13 extending across the machine below the pad pan 4. A handle 14 is connected with the die carrier 9 by the stem 15a and die lock or clamp arm 15 passing through the die carrier 9 and anchored in the handle, whereby a turning connection of the handle with the die carrier is obtained. The lock or clamp arm 15 is within a recess 16 in the under side of the die carrier and is operative by the handle 14 to engage and secure the die plate to the die carrier. The extent of turning movements of the handle 14 is limited by a disc 14' attached to the. handle and providedwth mately one-fourth of a revolution.

The machine is arranged to receive di plates having marking 4dies of dililerent de signs adapted to mark the ymaterials placed on the gage plate for subsequent work or operation. One such die plate 17a is shown and is provided with a pair of spaced projections 18 arranged to extend upwardly into the recess 16 so that the ends of the die lock or clamp arm 15 may engage under the projections 18 to secure the die plate to the carrier. Each die plate 17 also has a number of upwardly projecting lugs 17 a arranged to enage in holes in the die carrier to locate the die plates properly and to cooperate with the lock or clamp arm to hold the die plates rigid on the carrier. The edges 19 (Fig. 5) of the die lock or clamp arm 15 are beveled so that they readily pass under the projections 18 and,by further turning of sai arm, will clamp the die plate firmly in connection with the carrier. The under side of the die plate 17 is provided with marking ldies 20 of proper conti iration and design, so that when the mac ine is opera-ted the material on the gage platewill be marked properly thereby. This machine may be readily operated by hand by use of the handle 14 to swing the' die carrier successively Jfrom the ink pad 5 to the pieces of materi-al successively placed on the gage plate; or, the machine may be operated by a treadle device.

As shown, a number of counterbalance weights 21 are rigid with the shaft 13 in a relationship in which said weights tend to support the die carrier in an intermedate position between the pad 5 and the gage pla-te for movement in either direction. The treadle connections comprise a treadle cord 22 extending over and attached to a pulley 23 rigid with the shaft 13. The cord 22 may be held from. slipping on the pulley by a clamping device 24 holding the -cord 22 in clamped connection with the pulley. The cord 22.crosses below the pulley 23 and has one end connected tothe forward end of a treadle 25 by a tensioning device 26, and the opposite end connected to the rear end of the treadle by a tensioning device 27. The tensioning 'devices are operative to take up the slack in the cord resulting` from continued use of the machine. Rocking of the treadle in vone direction will swing the die carrier to inking position and in the opposite direction will swing the die carrier to marking position. 4Vhen both the treadle and the handle 14 are released the counterbalance weights 21 raise the die carrier to inermediate position ready for further operaions.

neaaeeo rIhis machine meets an existing need by greatly expediting and reducing the cost of operations, and also by producing the markings in the precise relationshi desired.

The machine may be manu actured without great cost and operated by unskilled operators.
